Definitions

  • This invention relates to an apparatus for transporting sheet-like recording carriers such as sheets of paper, envelopes or the like.
  • a transporting apparatus may be, for example, an assembly of an automatic recorder, a printer, or the like.
  • the recording carriers may be, for example, sheets of writing paper, cards, envelopes or the like.
  • the conventional machines automatically feed single sheets of paper such that when the printing is finished upon one such sheet, an identical blank sheet immediately follows and is thus quickly positioned for further printing.
  • This continuous flow of paper sheets thus provides for the automatic feeding and positioning of single sheets without the necessity of these sheets being manually positioned, thereby reducing the overall time required to accomplish a given task.
  • the conventional automated business machines do not always feed the required single sheets of paper. Often, a plurality of sheets are fed into the machine causing blockage of the conveying path as the sheets move through the machine. Thus, the blockage resulting from the plurality of sheets causes the machine to malfunction. The improperly fed sheets must be manually removed from the conveying path prior to the machine being, once again, ready for proper operation.
  • a transporting apparatus for sheet-like recording carriers which makes possible a continuous conveyance of single sheets of recording carriers and/or envelopes of variable thickness.
  • the sheets are singularly separated from a supply stack and are conveyed to a platen without special adaptation of the apparatus to the particular thickness of recording carrier being used.
  • the apparatus according to the present invention provides for the conveyed sheets and/or envelopes to be held by the deflecting plane against a baffle plate. In this manner, a possibly prematurely conveyed sheet is detained at its advancing edge at the edge of the baffle plate until the preceding sheet is conveyed past the baffle plate. The sheet thus obtained may then jump the baffle plate with its front edge, whereby it is likewise deflected by the deflecting plane and is held in a similar manner against the baffle plate.
  • Sheets and envelopes to be printed upon may be stacked alternatingly by such a device in the supply stack and then fed continuously to the platen. In this manner, letters and their corresponding envelopes, for example, may be quickly and efficiently prepared and collated. By utilizing the present invention, a resetting for different thicknesses is not necessary. Similarly, it is also possible to convey sheets or cards of variable thicknesses in any sequence.
  • the baffle plate may have a plane which, as compared to the vertical, is angularly slanted in the direction of the path of conveyance. As a result of the slanting position, it is easier for the sheet being detained to jump the baffle plate with its forward edge when a previously conveyed sheet vacates.
  • the baffle plate is to be disposed in the immediate vicinity of the stop surface, it is preferable that the baffle plate is attached to the element having the stop surface. More preferably, the baffle plate may be disposed in the middle of the conveying path in order to ensure a symmetrical load of the sheets to be conveyed during their separation.
  • the deflecting element may also be rearwardly extended in the direction of the supply stack and may be arched away from the supply stack.
  • This embodiment thus provides an intake slot or gap between the surface of the deflecting element and the element having the stop surface.
  • the intake gap should be selected large enough so that even thick recording carriers are conveyed easily. This intake gap, therefore, serves for supporting the separating device, in which an upward by-pass of the sheets pulled off the supply stack, is prevented.
  • FIG. 1 shows an apparatus for transporting sheet-like recording carriers with a planar deflecting surface
  • FIG. 2 shows a similar apparatus having an arched deflecting surface and an intake gap
  • FIG. 3 shows a similar apparatus having a planar deflecting surface and a limiting element for the intake gap, independent of the deflecting surface.
  • FIG. 1 there is shown a supply stack 10 of recording carriers, such as for example, sheets, cards and/or envelopes.
  • a bias is exerted on this supply stack 10, by means of fixedly supported springs 12, through a base plate 14, against a set of conveying rollers 18, consisting of at least two rollers, disposed on a common shaft 16.
  • the forward plane defined by supply stack 10, abuts the stop element 20 in the direction of the path of conveyance.
  • the top edge 22, of stop element 20 is slightly below the top sheet 24 of supply stack 10.
  • the relative position of the top sheet 24 is determined by the position of the set of conveying rollers 18.
  • a baffle plate 26, projecting into the path of conveyance of the sheet 24 is fixedly attached to stop element 20.
  • Baffle plate 26 has a surface 28 with a top edge 30.
  • Surface 28, relative to the perpendicular of the direction of the path of conveyance 32 is angled in the direction of the path of conveyance.
  • Edge 30 projects slightly into the path of conveyance of sheet 24.
  • Deflecting surface 34 is inserted after the baffle plate 26 in the direction of the path of conveyance 32. This deflecting surface 34 is angled relative to the original direction of the path of conveyance 32, in order to deflect the conveyed sheet such that it is held against edge 30 of baffle plate 26. The deflecting surface 34 is directed tangentially of the intake side of platen 36.
  • the set of rolls 18 is driven in the direction of rotation 46, and always pulls off the top sheet 24 from the supply stack 10 in the direction of conveyance 32.
  • the conveyed sheet is guided over the top edge 30 of the baffle plate 26 and is deflected by the deflecting surface 34 toward the platen 36.
  • a bending force is exerted on the sheet 24, as a result of which the latter touchingly crosses the edge 30 of the baffle plate 26.
  • the sheet lying beneath sheet 24 be pulled along through friction, then its leading edge will abut against the surface 28 of the baffle plate 26 below the edge 30.
  • the distance between the stop element 20 and the baffle plate 26 is relatively small, so that the abutting sheet despite friction on the conveyed sheet 24 lying above it, may not bend.
  • the leading edge of the sheet which is pulled along is guided upward, but is held back at the edge 30 of the baffle plate 26, until the conveyed sheet 24 has passed the baffle plate 26. Only then can the sheet which was pulled along, pass with its leading edge, the edge 30 of the baffle plate 26.
  • the separating device consisting of the elements 26, 28, 30 and 34
  • particular importance is to be assigned to the tilted positioning of the surface 28 of the baffle plate 26.
  • the edge 30 obviously must be angular relative to the surface 28 of the baffle plate 26.
  • the baffle plate 26 and the deflecting surface 34 are disposed in the middle of the sheets that are to be conveyed and must be synchronized in their width.
  • this separating device makes possible a reliable separation of sheets, cards and/or envelops of variable thickness.
  • FIG. 2 shows another embodiment, whereby the deflecting surface 48, is arched and extended in the direction of the supply stack 10, so that, together with the top edge 22 of the stop element 20, an intake gap 50 into the path of conveyance is formed. Furthermore, the extension 52 of the deflecting surface 48 is developed such, that a funnel-like intake is formed above the supply stack 10.
  • FIG. 3 shows an additional embodiment, in which an intake surface 54 is disposed above the supply stack 10 independently of the deflecting surface 34.
  • a baffle plate 56 is disposed independently of the contact element 20.
  • the arrangement shown may also be arranged inversely relative to the stop element 20, the baffle plate 26 and the deflecting surface 34, whenever the set of rolls 18 is beneath the supply stack, so that the bottom sheet of such an embodiment is carried away from the supply stack.
  • the baffle plate 26, 56 and the deflecting surface 34, 48 are disposed rigidly relative to the stop element 20.
  • the separating device has no movable parts and is, therefore, very simple in its structure despite its campatability with recording carriers of variable thickness.
  • a separating device of the present invention may be attached subsequently to existing transportation arrangements.
